Videogames are electronic games that involve interaction with a user interface, to generate a visual feedback on a screen. The systems used to play videogames are known as Platforms, these can vary from computers to machines made specifically for the purpose of playing. One of the most important parts of videogames (as a unit) is the Controller, which is the input device used to manipulate the videogame, which has changed throughout time, it started as a joystich and a button, and now (generally) it has 2 joysticks, a 4 direction pad, and 4 buttons; sometimes, in computers, the user can play with a keyboard and mouse. Most of the time videogames use other ways of providing interaction and information to the player, one option is audio, which is universal, and is used to set the mood. The latest consoles contain haptic peripheral feedback, such as vibration, used to get the feeling of being involved in the game, which helps to feel as if you were inside the game.
Videogames are more than fictional stories full of death and violence, there are many kinds of videogames, each with their ESRB (Entertainment Software Rating Board) rating. According to the content there are 7 ratings in total, the first is “Early Childhood” (EC) which is used when the videogames are suitable for ages 3 and older, because they don’t contain material that could be inappropriate for parent, also, there is “Everyone” (E) which may be suitable for years 6 and older; the games in this category contain minimal violence and usage of mild language. “teen” (T) is used for ages 13 and older, even though these games contain violence and crude humor, they have minimal blood and strong language, whereas, “M” (mature) contain blood, sexual content and violence, and it’s for ages 17 and older. “Adults Only” (AO) games are quite scarce, but contain scenes of intense violence, graphic and sexual content; these games are only suited (as the rating states) for people over 18 years
